How would a fluid with a high solute concentration affect osmotic pressure when compared to water?
Fluid with a high solute concentration would be hyper-osmotic compared to water, and thus would be expected to exert osmotic pressure if separated from pure water with a semipermeable membrane.
Is increasing osmotic pressure within joint a function of synovial fluid?
No, increasing osmotic pressure within a joint is not a function of synovial fluid. Osmotic pressure is the force that drives the movement of water across a semipermeable membrane, and it is determined by solute concentration. The synovial fluid's main function is to lubricate and nourish the joint, not to influence osmotic pressure.
Which force favors blood filtration?
Capillary hydrostatic pressure and interstitial fluid osmotic pressure
The primary means of water movement between fluid compartments is?
The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
Osmotic pressure is created by the presence in a fluid of small difusible moleules that easily move through the capillary membrane?
Osmotic pressure is the force exerted by the movement of solvent molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement equalizes the concentration on both sides of the membrane. The osmotic pressure is directly proportional to the concentration of solute particles in the fluid.
Starvation causes the plasma protein levels in the blood plasme to fall how would that affect the formation of tissue fluid in the tissue spaces?
Starvation causes the plasma protein levels to decrease, and when there is less plasma protein in the blood, you get lower Po (Osmotic Pressure). Lower osmotic pressure means less pull (of tissue fluid) so this causes generalized edema.so basically, less plasma proteins -> decreased Po -> less pull -> reduced venous clearance --> fluid build up in tissue
How does potassium affect osmotic pressure?
same as other ions. Note that in your body potassium salts within cells balances the osmotic pressure of sodium salts in the extracellular fluid.

The hydrostatic pressure of blood in a capillary is 19 mmHg and that of the tissue fluid is 1 mmHg while the colloid osmotic pressure of the blood is 23 mmHg and that of the tissue fluid is 0 mm Hg?
taken up; -5 mmHg
Is increasing osmotic pressure within joint a function of synovial fluid?
No, increasing osmotic pressure within a joint is not a function of synovial fluid.

The synovial fluid's main function is to lubricate and nourish the joint, not to influence osmotic pressure.
What causes the transfer of materials between capillaries and tissue fluid?
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
Which forces affect the exchange of substances between blood and tissue fluid?
At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.
Which net pressure draws fluid into the capillary?
net osmotic pressure
The fluid that is forced out of the capillary beds by hydrostatic and osmotic pressures and into the tissue spaces is called?
interstitial fluid
What is Starling's Law of the capillaries?
The hypothesis that fluid filtration through capillary membranes is dependent on the balance between the pressure the blood places on the membranes and the osmotic pressure of the membranes. The law relating to the passage of fluid out of a capillary depending on the hydrostatic and osmotic pressures of the blood and the same pressures of tissue fluid, the net effect of the opposing pressures determining the direction and rate of flow.
What reflects balance between the direction and amount of fluid that flows across capillary walls?
Hydrostatic and osmotic pressure.
Which force favors blood filtration?
Capillary hydrostatic pressure and interstitial fluid osmotic pressure
